2017 Honda Ridgeline. The Honda Ridgeline is a unique pickup that employs car-like unibody construction in place of the rugged but unrefined body-on-frame setup that underpins its competitors. As a result, the Ridgeline provides a more comfortable ride and better handling than most pickups while still offering decent towing and hauling capabilities.
The flatness tolerance references two parallel planes (parallel to the surface that it is called out on) that define a zone where the entire reference surface must lie. Flatness tolerance is always less than the dimensional tolerance associated with it. Tolerance Zone: Two Sets of Parallel Planes where the entire referenced surface must lie. Gauging / Measurement: Flatness is can be measured using a height gauge run across the surface of the part if only the reference feature is held parallel.
A close approximation of the arithmetic average roughness-height can be calculated from the profile chart of the surface. Averaging from a mean centerline may also be automatically performed by electronic instruments using appropriate circuitry through a meter or chart recorder.oughness width cut off is the greatest spacing of respective surface irregularities to be included in the measurement of the average roughness height. It should always be greater than the roughness width in order to obtain the total roughness height rating.
